The invention provides a method and a system of using cell phone mobile data to evaluate intersection signal control efficiency. A detection range is set in an electronic map comprising an intersection requiring evaluation of traffic efficiency of signal control efficiency, and the starting line of the detection range is superposed with an intersection stopping line, and the preset distance of the upstream of the stopping line is covered by the detection range. Cell phone data of all of cell phones in the detection range is acquired in a real-time manner, and comprises the ID numbers, the positions, and the moving speeds of the cell phones, and then the cell phone data of every cell phone is associated with the electronic map. The number of the cell phones stagnated in the detection range during red light time of each direction and the stagnated time of each cell phone are calculated accurately according to the cell phone data, and therefore the total stagnated time of the cell phones waiting for the red light is calculated, and is used as a total waiting time. Whether the intersection signal lamp control efficiency is ideal is evaluated according to a ratio between the red light waiting times of two directions, and the signal lamp efficiency is evaluated in a quantitative way.

The invention discloses a method for evaluating the surface cleanliness of a metal base material for construction and forming. According to the test results, the weight coefficients corresponding to oil stains, particles, and chips are set, and different methods are used to detect the pollution scores of different pollutants. Value, by calculating the product sum of all pollution weight coefficients and pollution scores, so as to quantitatively characterize its surface cleanliness. The invention proposes an accurate and systematic evaluation method of surface cleanliness for metal substrate construction and forming. Determine the weight coefficient of pollutants based on the degree of adverse effects of different pollutants on the healing of the substrate interface; adopt different detection methods for different pollutants, and determine the pollution scores of different pollutants; the weight coefficient of each pollutant The product and the pollution score are summed to determine the pollution value, and a comparison relationship is established to finally determine the cleanliness level, thereby accurately and quantitatively evaluating the surface cleanliness of the substrate.
